To all whom it may concern: I I Be it known that I, ARTHUR L. Boson, of

Elizabeth, in the countyof Union, and in the State of New Jersey,.haveinvented a certain new and useful Improvement in SubmarineTdrpedo-Tube.Construction, and do herebydeclare that thefollowingisafull, clear, and exact description thereof.

My invention relates particularly to submarine boats, and is adaptedespecially for submarine boats designed and used for purposes of war. i

The object of my invention is to provide a submarine which is compact,and which may be, if desired, of comparatively small size so that thesame can be carried upon or in battleships or cruisers, and which mayalso be .usedin shallow waters.

A further object of my invention is to lo cate the torpedo tubes in sucha manner as to provide an advantageousarrangement of the space withinthe submarine, said torpedotubes being preferably located at least inpart outside of the curvature of the main portion of the hull.

This application is a division of my copending application, Serial No.56,656, filed October 19, 1915, and entitled Submarine.

While my invention is capable of embodiment in many different forms, forthe purposes of illustration I have shown only one form thereof in theaccompanying drawings, in which Figure 1 is a plan view of a submarinemade in accordance with my invention; and

Figs. 2, 3, 4 and 5 are sectional views taken respectively on lines 22,33, H and 55, Fig. 1, looking in the direction of the arrows.

In the drawings I have shown a submarine having a hull portion 1, thewalls of which have a general regular curvature, that is, thecross-section of the submarine may be of a general circular, orelliptical shape as shown in Figs. 2 to 5. As the particular characterof the whole submarine construction is not essential to the presentinvention, the same will not be described in greater detail.

In order to provide as small a displacement as possible, and toeconomize space in the interior of the hull, I arrange the torpedo tube,or tubes, so that the space within the hull is not taken up to anyextent thereby, and at the same time the displacement ofthe submarineisv not unduly increased. 1

. At the point where the torpedo tube :2 is to be located, the adjacentportion of the hull is bulged outwardly beyond the gen-. eral curvatureof the hull to provide a pocket 3, the walls 4 inclose the tube asclosely as practicable. In the form illustrated, this pocket is formedby a trough-like section 4 ofthe casing, suitably secured to theremainder of the hull 1 which latter is of regular curvature. It is alsoadvantageous to arrange the pocket 3 at the top of the submarine, andwith its axis substantially in a central longitudinal plane, as shown inthe drawings. 3. Although my invention may be employed in connectionwith any desired number of torpedo tubes, it is particularly adapted toa construction in which two opposed tubes are located in line with eachother. In the form illustrated a second torpedo tube 5 is located inline with the tube 2, and the bulged-out portion 4 of the hull is madeto extend substantially the entire length of the submarine so as toprovide a pocket 3 which is long enough to receive both tubes 2 and 5.

With the submarine constructed in accordance with the invention abovedescribed, it will be noted that the torpedo tube, or tubes, do notproject to any extent into the space within the hull and yet the totaldisplacement of the submarine is not unduly increased, since the pocketprovided by the bulged-out walls takes up no more volume than isabsolutely necessary. The above features of the construction areparticularly advantageous in types of boats which are to be auxiliary tolarger craft, or to be operated in shallow water, or with a smallnumbered crew.

While I have described a specific form of the invention, it will beobvious that many changes may be made without departing from theprinciple thereof, as defined in the appended claims.

I claim 1. In a submarine, the combination of a hull having a generalregular curvature, a torpedo tube located within said hull and closelyadjacent the walls thereof along substantially its entire length, thatportion of the hull which incloses said tube being bulged outwardlybeyond the general curva ture of the hull, to provide a pocketcontaining said tube.

2. In a submarine, the combination of a hull having a general regularcurvature, a torpedo tube located within said hull and closely adjacentthe walls thereof along substantially its entire length, the axis ofsaid tube being disposed substantially in a.cen tral longitudinal planeand at the top of the submarine, that portion of the hull which inclosessaid tube being bulged outwardly beyond the general curvature of thehull, to provide a pocket containing said tube.

3. In a submarine, the combination of a hull having a general regularcurvature, a

' torpedo tube located within said hull and closely adjacent the wallsthereof along substantially its entire length, that portion of the hullwhich incloses said tube being bulged outwardly beyond the generalcurva- V ture of the hull, to provide a pocket containing said tube, anda similarly arranged, op positely directed torpedo tube located in linewith said first mentioned tube.

4. In a submarine, the combination of a hull having a general regularcurvature, a

torpedo tube located within said hull and closely adjacent the wallsthereof along substantially its entire length, the axis of said tubebeing disposed substantially in a central longitudinal plane and at thetop of the submarine, that portion of the hull which incloses said tubebeing bulged outwardly y d, h ge e l. r t re of; the. 11111,. provide apocket containing said tube, and a similarly arranged, oppositelydirected torpedo tube located in line with said first mentioned tube.

5. In a submarine, the combination of a hull having a generalregularcurvature, a portion of the walls of said hull in a planeparallel to the longitudinal axis of the submarine, being bulgedoutwardly beyond the general. curvature of the hull to provide alongitudinal pocketextending substantially the entire length of thesubmarine, and a pair of oppositely extending torpedov tubes located insaid pocket.

6. In a submarine, the combinationof a hull having a general regularcurvature, the
